BREMERTON, Wash. (AP) — A 17-year-old was arrested Saturday in the death and sexual assault of a 6-year-old girl whose body was found near the Washington state mobile home park she vanished from last weekend, authorities said.

The boy was arrested without incident by deputies and FBI agents at his home in the same Bremerton-area mobile home park, Kitsap County sheriff's Detective Earl Smith said at a news conference.

The Washington state crime lab made positive confirmation of the suspect through forensic evidence. Earlier in the week, the sheriff's office had collected DNA cheek swabs from dozens of nearby residents.

Smith said Saturday that the boy was being interviewed and will be booked with second-degree murder, manslaughter and rape in the girl's death.

The FBI's Specialty Search Dogs Unit discovered the body of Jenise Paulette Wright on Thursday amid thick brush in a wooded area near the trailer park. Volunteer canine search teams had previously reported that their dogs had showed interest in a particular area.
